SETTlNG-GAGE FOR CREAM-SEPARATORS.

Specification of Letters Patent.

Patented April 16, 1907.

Application filed May 9, 1906. Serial No. 316,013.

ing had therein to the accompanying draw- 1ngs.

This invention relates to gages for accurately joining together the parts of a creamseparator, and is especially adapted for use with the separator known as the Sharpless cream-separator.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a front view of a separator with my gage in place thereon. Fig. 2 is a plan of my improved gage. Fig. 3 is a front elevation thereof, and Fig. 4 is an end elevation thereof.

Similar numerals of reference refer to similar parts throughout the several views.

In a separator of the class for which this invention is particularly designed the spindle 1 rotates at a very high rate of speed and is joined to the rotating separator-tube 2 by a hollow conical nut 3. These parts must be removed for cleaning every time the machine is used, and as a result of the frequent screwing of the nut 3 it becomes slightly worn after several months use. When the nut becomes worn, it is very difficult to get the spindle 1 and the tube 2 absolutely coaxial,

and if they are at all out of alinement the tube 2 will vibrate violently, especially since the rate of rotation is very high. In order to overcome this difficulty, I have devised the following gage, by means of which the parts may be quickly and accurately set up. This gage consists of a horizontal plate of metal 4, having two slots 5 near its ends, one or both ofsaid slots being covered by an adjustable plate 6, having a smaller slot 7 therein, said slot 7 being adapted to fit over the lugs 8 on the arms 9, which are secured to the side of the separator and which support the removable milk-tank. A crossplate 10 is adjustably secured to one'end of the plate 4 and extends out sidewise therefrom, said extension 11 being offset downward and having a curved edge adapted to fit around the nut 3.

The gage is operated as follows: The milktank not yet having been placed in position on the arms 9, the plate 4 is placed thereon, the lugs 8 passing through the slots in the plate 4 and in the adjusting-plates 6. Then the nut 3 is loosely secured to the tube 2 and the spindle 1 is slowly rotated. When the plate 4 is in the position described, the extension 11 of the cross-plate 10 fits around the edge of the nut 3 if it is in its proper position. As the nut 3 is then rotated slowly it-may be seen whether it is exactly in alinement with the spindle 1 and the tube 2, and if it is not it can be quickly adjusted and the parts tightened up. Then the gage is removed and the milk-tank is placed in position on the arms 9 and the separation is ready for use.

Having described my invention, what I claim is 1. A separator-setting-up gage, comprising a plate adapted to be loosely supported on the separator, a plate adjustably secured thereto and having a slot adapted to receive a lug on the separator to hold sa'idfirst plate in position, and an offset cross-plate secured to said first plate and projecting adjacent to the rotating spindle.

2. A separator-setting-up gage, comprising a plate adapted to be loosely supported on the separator, a plate adjustably secured thereto and having a slot adapted to receive a log on the separator to hold said first plate in position, and an offset cross-plate adjustably secured to said first plate and projecting adjacent to the rotating spindle.

In testimony whereof I my signature in presence of two witnesses.
